|Title||BLUE COMPACT DWARF GALAXY VIIZW403|
|Author||Dr KIYOSHI HAYASHIDA|
|Description||VIIZw403 is one of the nearest blue compact dwarf galaxies with extremely low metallicity of 1-22-1-15 solar. We found a point-like source about 0.3 arcmin apart from the center of the galaxy in the Chandra archived data. Emission line of Oxygen is clearly visible in the X-ray spectrum of the source, indicating the thermal emission from hot optically thin plasma. The X-ray luminosity of Lxvirgul10e38 erg-s, much higher than typical galactic SNRs, pauses a question on its nature. We will obtain high quality X-ray spectrum with the XMM-Newton. Metal abundance determined in the observation will illustrate the origin of hot gas in galaxies, in its simplified case.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
